IPC: C22C9/04
Filed: 1983-09-07
Abstract: PURPOSE:To provide a copper-base alloy which has excellent corrosion resistance and machineability and good workability and hot forgeability by incorporating Cu, Pb, Sn and P respectively at prescribed ratios into said alloy and consisting of the balance Zn and unavoidable impurities. CONSTITUTION:A copper-base alloy consists, by weight, of 58-63% Cu, 1.0- 2.0% Pb, 0.4-1.5% Sn, 0.01-0.1% P and the balance Zn and unavoidable impurities. This copper-base alloy has the characteristic in that the resistance to dezincification corrosion indicated by the dezincification ratio (gamma value) of the equation I and the total corrosion weight loss (DELTAT) of the equation II is remarkably improved as a corrosion resistance characteristic. Such improvement is attained mainly by adding P to the alloy in the prescribed range. The alloy exhibits also the excellent machineability by a machining test or punching test, good elongation and high workability. The copper-base alloy is therefore extremely suitable as a material for valve parts and in resembling fields.

Title: Magnetic recording medium
Inventor: ISHIDA TOSHIO
IPC: C09D5/23
Filed: 1989-06-27
Abstract: PURPOSE:To obtain a medium which always has stable traveling durability even under severe conditions such as high temp. and high humidity, low temp. and low humidity by incorporating an ammonium salt of specified substd. or unsbstd. phosphite into the magnetic layer or the surface of the magnetic layer. CONSTITUTION:The magnetic layer of the surface of the magnetic layer contains an ammonium salt of substd. or unsubstd. phosphite expressed by formula I. R and R' represent same or different bydrocarbon groups with 10-26 carbon atoms and R<1>-R<4> are same or different hydrogen or hydrocarbon group with >1 carbon. Since unsubstd. ammonium ion having high alkalinity interacts with phosphorous group as anion part and easily orients, it gives significant effect of lubrication. With more substitution of ammonium ion for nitrogen, the salt becomes more stable. Thus, since the quaternary ammonium salt is particularly stable, the obtd. medium maintains its characteristics during stored under severe conditions and has stable traveling property.

Title: Powder baking method of incineration ash
Inventor: TAKAHASHI SHIRO
IPC: B09B3/00
Filed: 1989-06-28
Abstract: PURPOSE:To inexpensively bake incineration ash without applying press molding thereto by receiving the powdery incineration ash of sludge or the like in a ceramics container to bake the same at specific temp. CONSTITUTION:The incineration ash incinerated in a sewage sludge incineration furnace is baked at 1000-1400 deg.C in a state received in a ceramics container in a powder form within a batchwise or continuous incineration furnace. In this case, oxide such as SiO2, Al2O3 or Fe2O3 is contained in the incineration ash of sewage sludge and, when the container is made of heat-resistant steel, oxidation reaction is generated between SiO2 or the like and iron of the container during baking to generate heat and the temp. of the container becomes high to generate the deformation and oxidative wt. reduction of the container and the container becomes unusable within a short period of time. The baked product is different in baking temp. between the direct contact part with the container and the other part to generate trouble such that not only baking becomes non-uniform but also a part of the baked product is bonded to the container to make it impossible to take out the baked product from the container. When incineration ash is received in the ceramics container to be baked, said trouble is not generated. Manufacturing cost is also reduced.

Title: Printing defect deciding method
Inventor: KUBOTA KEIICHI
IPC: B41F33/14
Filed: 1993-06-14
Abstract: PURPOSE:To prevent an erroneous detection of a printing defect due to dampening water, etc., and to detect and decide the printing defect to be a true defective print sheet by deciding the defect when a defect is detected on either front or rear surface of a water permeable printed matter and deciding no defect when defects are detected in corresponding areas of both the surfaces. CONSTITUTION:Printing element densities of columns E1-H1, E2-H2 of rear surfaces of a printed newspaper are inspected and measured by an imaging unit 20, and signals are sent to a signal deciding unit 28. Similarly, in the case of colunms A1-D1, A2-D2, signals are sent to the unit 28. The unit 28 compares printing elements of the front and rear surfaces of a printed matter fed via the unit 20 with a fundamental printing element, and sends, when there is a defect, a defect signal to an output unit 34. When the unit 28 decides the defect signals at corresponding positions of both sides of the matter, it decides that no defect exists due to the defect signals due to drop of water. When the signal is detected only on one side of the matter, it is decided as being a defect by ink, and the matter is decided as being a defective printed sheet.

Filed: 1985-07-29
Abstract: PURPOSE:To enable the operation at ultralow speed by synchronously operating in harmonic wave at low speed operating tim with a relation of Z2=Z1+P among rotor slot number Z2, stator slot number Z1 and pole number P. CONSTITUTION:A squirrel-cage induction motor generates a verylarge synchro nous torque with a slip of S=1-P/Z2 when Z2=Z1+P is satisfied among rotor slot number Z2, stator slot number Z1 and pole number P. For example, the slip for generating large harmonic wave synchronous torque Ts becomes 0.9 as shown under the condition, for example, of 3-phase squirrel-cage induction motor, 5.5kW, 4-pole 200V, 50Hz, stator slots Z1=36, rotor slot number Z2=40, constant torque 35(N-m). Thus, a frequency control by an inverter is performed in the operating state by utilizing a harmonic torque generated at the slip near 1 to suitably operate from low to ultrahigh speeds.
